In cylinder printing, wherein the printed sheet is positioned on the cylinder, it is often necessary to remove the printed sheet to make some changes therein before the final printing is accomplished. The cylinder usually has positioned thereon manilla packing sheets on which the printed sheet is laid. When the printed sheet has been removed, it is necessary that it be replaced on the packing sheets in the exact relation thereto that it was before it was removed.

It is an object of this invention, therefore, to provide a V-shaped marking guide that will so mark the packing sheets and printed sheet that it is very simple to replace the printed sheet on the packing sheets in the exact relation to each other that they were before the printed sheet wasremoved.

Another object of the invention is to provide a V-shaped marking guide that is simple in construction, eflicient in operation and inexpensive to manufacture.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing, in which:

Fig. 1 is an elevational view of the V-shaped marking guide embodying the invention, with the marker retracted;

Fig. 2 is a view similar to Fig. 1, with the marker extended;

Fig. 3 is an enlarged longitudinal sectional view of the marking guide of Fig. 1;

Fig. 4 is a vertical sectional view on the line 4--4 of Fig. 3;

Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 3;

Fig. 6 is a bottom plan view of the marking guide of Fig. l; and

-Fig. 7 is a detailed fragmentary sectional view of the marker.

Referring more in detail to the drawing, wherein like parts are designated by like reference numerals, the reference numeral 10 is used to generally designate a V-shaped marking guide embodying the invention.

The V-shaped marking guide 10 comprises a cylindrical housing 11 which has a reduced neck portion 12 that is integral therewith. The outer surface of the housing 11 is partially knurled as at 13 and a V-shaped sight mark 14 is provided in the periphery of the outer end of the housing 11.

The housing 11 has a partition 16 therein which forms a dividing wall between the internal bore 17 of the housing and a reduced internal bore 18 of the neck portion 12. A guideway 19 is provided in the center of the partition 16 and the guideway 19 forms a direct communication between the bore 17 in the housing 11, and the bore 18 in the neck portion 12. The outer end of the neck portion 12 is also provided with a circular recess atent ice A V-shaped marker 21 is positioned in the bore 17 of the housing 11. The outer end of the marker 21 is bevelled as shown at 22 in Fig. 7, and a guide stem 23 is secured to the inner end thereof. Screw threads 24 are provided on the stern 23 adjacent the outer end thereof and the outermost end of the stem 23 is provided with a bead 25.

A knurled nut 26 is threadably mounted. on the stem 23 and has a reduced annular shoulder 27 on the inner side thereof that is adapted to be seated in the recess 20 in the neck portion 12. An Allen screw 28 is threaded into a threaded bore 29 that extends transversely through the nut 26 so that the screw 28 will engage the screw threads 24 on the stem 23 to retain the nut 26 in fixed relation to the stem 23.

A coil spring 30 is positioned in the bore 18 of the neck portion 12 in circumjacent relation to the stem 23. The inner end of the spring 30 abuts the partition 16 and the outer end thereof abuts the annular shoulder 27 of the nut 26. The spring 30 tensions the nut 26 so that the marker 21 is retracted within the housing 11.

A hex-shaped keeper nut 31 is positioned over the outermost end of the stem 23. The nut 31 has an internal bore 32 that is provided with an annular rib 33, and when the nut 31 is forced onto the end of the stem 23, the rib 33 will be positioned rearwardly of the bead 25 on the stem 23 to retain the nut in movable relation to the stem 23.

In operation, the apex 34 of the V-shaped marker 21 is alined with the V-shaped sight mark 14 in the housing 11. The guide 10 is then positioned on the packing sheets and printed sheet at the desired location where a mark is to be made. The nut 31 is then depressed against the action of the spring 30. The stem 23 will extend the marker 21 as in Fig. 2 and a mark will be made. The nut 26 is adjusted on the threads 24 to limit the extension of the marker 21 and thus determine the depth of the mark made in the packing sheets and printed sheet. After the nut 26 has been adjusted on the stem 23, the Allen screw 28 is threaded into the bore 29 to retain the nut 26 in fixed relation to the stem 23. As the marker 21 is extended, the annular shoulder 27 will be seated in the circular recess 20 in the neck portion 12.

There has thus been provided a V-shaped marking guide that will efficiently carry out the function for which it has been designed and it is believed that from the foregoing description the operation and construction of the guide will be apparent to those skilled in the art and it is also to be understood that changes in the minor de tails of construction, arrangement and combination of parts may be resorted to provided they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

A marking guide comprising a cylindrical housing having an integral reduced neck portion at one end thereof, a knurled portion adjacent the reduced neck portion and a V-shaped sight mark in the periphery of the housing adjacent the end thereof opposite to the end having the reduced neck portion thereon, said housing having an internal bore therein, said reduced neck portion having a reduced internal bore therein, a partition in said housing having a guideway in the center thereof forming a dividing wall between the internal bore in said housing and the internal bore in said reduced neck portion and said guideway forms a direct communication between said bores, a circular recess in the outer end of said reduced neck portion of greater diameter than the bore in said portion and communicating therewith, a V-shaped marker positioned in the bore in said housing so that the vertex of said marker will be in aiinement with the sight mark on said housing, the outer end of said marker being bevelled and a guide stem is secured to said marker opposite to the vertex thereof, said guide stem is adapted to extend through said guideway and that portion'of said stern ad- 'jacent the outer end thereof is provided with external threads, a bead on the outer endof said stem, a nut having a reduced annular shoulder on the inner side thereof that is adapted to enter the recess in said reduced neck portion threadably mounted on said stem, a screw member threadably mounted in said nut at right angles to said stem and adapted to engage the threads on said stem, a coil spring positioned in the bore in said reduced neck portion in ciroumjacent relation to said stem and intermediate of said partition and the reduced portion on said nut, and a hex-shaped nut retainer having an internal bore provided with an annular rib positioned over the bead on said stem so that said rib is positioned rearwardiy of said bead to retain said nut retainer on said stem.
